ECOTAP VPD FOR DISPERSED GENERATION UNITS


For integration into the grid, local generation plants based on renewable energies (photovoltaics, wind, biogas) must meet the local requirements of grid operators in the form of the applicable grid connection conditions. These grid connection conditions frequently oblige the manufacturers to demonstrate the electrical properties of the systems and require type tests. The provision of reactive power, which depends on grid voltage, is especially critical. Particularly when underexcited, the ability of the generation plants to provide reactive power is limited in the event of undervoltage.

VOLTAGE REGULATION TRANSFORMERS IMPROVE REACTIVE POWER CAPABILITY.

Voltage regulation transformers with ECOTAP VPD ensure that generation plants, such as wind turbines or PV parks, are always supplied with nominal voltage and use can thereby be made of full reactive power capability. So there is no need to oversize the converters, reduce the active power feed-in or even provide any external reactive power compensation system which may have otherwise been required. Using a transformer with ECOTAP VPD voltage regulation therefore produces a more economical generation plant. Alternatively, the free space obtained by using the transformer can also be used for an existing generation plant with a higher performance class.

 

 

 

 

 

 

BENEFITS FOR YOU
AT A GLANCE:

  • The transformers can be combined with all driveline concepts (e.g. asynchronous generators, full-scale inverters).
  • The voltage regulation transformer can either run on its own or be integrated in the generation unit's regulation system.
  • Responds to changes in voltage in a matter of seconds and thereby guarantees that the times in which reactive power needs to be made available are always met
  • Long lasting and maintenance free thanks to tried-and-tested MR vacuum technology
  • Incorporates MR's unique operating experience with on-load tap-changers
  • Large regulating range yet fine grading of regulation steps
  • Global MR service network
